The finale stage of 'WIN' was met with a flood of tears by the members of Team A (Kang Seung Yoon, Song Min Ho, Kim Jin Woo, Lee Seung Hoon, Nam Tae Hyun) and Team B (B.I, Kim Jin Hwan, Bobby, Song Yoon Hyung, Goo Jun Hee, Kim Dong Hyuk). Though Team A will move on to become YG Entertainment's next idol group, WINNER, all the trainees were devastated to say goodbye to the journey and their fellow competitors. As Yang Hyun Suk announced previously, Team B may be disbanded.

On the live broadcast, Team A and Team B's final mission was a self-composed song, original choreography, and a cover of producer Teddy's track "Just Another Boy". The winning team was determined fully by viewer votes. Team A beat Team B in both rounds of voting with a 2.74% difference in the first round and a 0.52% difference in the second.
